7 Claims.

This invention relates to a dispensing device for liquid containers, thegeneral object of the invention being to provide means for dispensinliquid from one container into another, with 7 means for causing the airin the receiving container to enter'the container from which the liquidis flowing so as to prevent a vacuum occurring in the last mentionedcontainer, with means for opening a valve in the dispensing 10 containerwhen the two containers are placed together.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to be here'-inafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

- In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a vertical sectional view through a dispensing' containershowing the [invention thereon, the section being taken on line 1-1ofFigure 2.

Figure 2 is a top plan view of the deviceshown in Figure 1. 7

Figure 3 is a top plan view of the dispensing device.

Figure 4 is a bottom plan view thereof.

Figure 5 is a side view thereof.

In the drawing the container in which the liquid is to be contained isshown at A, is made in the form of a bottle and the dispensing device isshown at B. This device is formed of rubber or the like and is providedwith a. flange 1 for engaging the mouth of the bottle andwith-a centralenlargement 2 on its upper face having a recess 3 therein which extendsinto a rounded enlargement 4 formed at the lower end of the device. Thebottom of the recess is spaced from the bottom face of the enlargement 4but a slit 5 is formed in the part 4 and passes through the 45.bottomwall of the recess, which is preferably rounded as shown. A pair of ribs11 is formed on the underside ofthe device B, one on each side of theslit. I These ribs extend at right angles to the slit from a point onthe enlargement 4 adjacentthe slit outwardly to a point slightlyspacedinwardly from edge of the flange 1 as is shown in Figure 4. Theresiliency of the device holds the slit closed, as shown in Figure 1,but when the enlargement 2 is forced inwardly, when the flange 1 isclamped between the bottle neck and the cap 6, the inner or lower partof the device B will be stretched, causing the walls of the slit tospread apart and this spreading apart of the walls of the slit isfacilitated by the ribs which resist the inward movement of the partsast Cleveland, Ohio 1932, Serial No. 627,660 (01. 215-74) 2 and 4. Thereis no actual distortion of the part 2 in the sense that its shapechanges, but the movement of the part 2 inwardly or upwardly, when thebottle is inverted, and pressure applied on the part 2, will cause thisopening of the slit. When the container is inverted the pressure of theliquid against the-bottom of the device will hold the slit closed sothat no liquid will escape when the container is in inverted position.The device is removably held on the top of the bottle by a screw cap 6having an opening in the top part through which the enlargement 2 passesand during shipment or when the device is not in use I provide a shield'7 having a flange 8 which is held against the flange 1 of the device bythe cap.

\ A tube 9 of glass or the like is placed in an opening 10 of the deviceon one side of the socket or recess 3 and extends close to the bottom ofthe container. I

When the device is to be used the shield '7 is removed and the bottle isinverted and the container which is to receive some of the contents ofthe bottle A has its mouth portion pressed over the enlargement 2. Thiswill cause upward movement of the parts 2 and 4 which will result in theopening of the slit, as before described, so

' that some of the contents of the bottle will flow through the deviceinto the container and the air in the container will flow up the tube 9and thus take the place of the liquid flowing from the bottle.

This will prevent sputtering or leaking of liquid around the opening ofthe receiving container and it also stops the flow of liquid from thecontainer A when the receiving container is filled.

As will be seen the device acts as a valve operated by diaphragm action,opening under the action of pressure and closing automatically when thepressure is released. It automatically stops the flow of liquid when thereceiving container is full and it will empty the dispensing containercompletely. Increasedpressure or an increased amount of liquid in thedispensing container serves to close the valve more securely.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

Having thus described my invention, what I claim as new is: Y
